Looks like a joke to me. For instance the picture on the mainpage:
This picture doesn't look like the thing a racist movement would put on it's mainpage, wasted white kids are not something to be proud of, not even for white supremacists.
Also, there's no actual download, and the only topic in the forum is about something that happened on another forum when they asked what race the developers of some program are.
Basically, looks like some kids who want attention to me.
